SPECIFICATION forming part of Lettersy Patent No. 400,388, dated 'March 26, 1889. Application filed July J 1888. Serial No. 280,518. (No model.)

Y siding at Peoria, in thel county of Peoria and v bar b, which is pivoted at its front end to ann State of Illinois, and a citizen of the United States, have invented a new and useful Improvenient in Oultivators, of which the following is a speciiication, reference being had to the accompanying drawings, in which- Figure l is a plan. Fig. 2 is a section at line 2 of Fig. l. Fig. 3 is an enlarged detail in perspective, showing the device by means of which the wheel is turned when the shovelbeam is moved either to the right or left. Fig. 4E is an enlarged detail showing a curved sleeve with shovel attached.

The leading objects of this invention are to provide improved devices for changing the direction in which thewheels travel when theline of travel of the shovels has changed by moving them either to theI right or to the left, and to provide an improved sleeve to which the shovels are attached, by the use of which, as the shovel is lowered, it will be more nearly perpendicular, and as it is raised, less so, which I accomplish as-illustrated in the drawings and hereinafter described.

That which I claim as new will be pointed out in the claim.'

In the drawings, A A represent an arched axle,which, as shown, is divided at the center, so that the two parts can be adjusted laterally.

B is the tongue.

C is a caster-wheel, which, as shown, is supported 4on a stud or axle, c, secured to the arm, c, which is rigidly secured to one part of the axle.

D represents one of the shovel-beams,which, as shown, consists of two parts, one of which carries a handle, H. The forward end of the beam is connected with a sleeve, oZ, which rotates upon one of the horizontal parts of the axle, as usual. E is the other shovel-beam, carrying a handle, I-I. The forward end is connected with a sleeve, e, upon a horizontal part of the axle. The shovel-beams 'have the usual vertical and lateral movements.

f is a sleeve rigidly secured to the outer end r 5ogof the horizontal portion of that part of the axle marked A. Connected with this sleeve f there is a slotted arm, g, which extends upward, and also a piece, h,which extends downward from the sleeve f.

F is one of the wheels supported on the short axle t', which extends out from a casting, j, which is held in place between the upper end of the part g and the part h by means of a bolt or pin which passes through j, on which pin the part j can rotate.

7c is an arm extending out from the part j, which arm is forked at its inner end.

Z is a link pivoted in the forked end of the arm Za. The other end of this link is provided with a hole.

'm is an arm which -is bolted to thel plowbeam E. At the outer end of the arm m is a hook or stud, n, which passes through theY hole in the link Z.

In use, if the shovel-beam E be moved to the right, the forward part of the wheel will be turned a little to the right, sufficiently to change its line of travel through the action of the arm in, link Z, arm 7c, and part j. The travel of the wheel F away from the right line will cause the caster-wheel C to move in the same direction, and both wheels and the frame will move to the right of the direct line of travel. A movement in that direction will be continued until the position of the shovels and the beam be changed. 'If this beam E be moved to the left of a right line, the action will be the opposite of that just described, the wheel F being moved to the left, and the caster-wheel and frame will follow.

G are sleeves of peculiar form, one of which is attached to each beam or part of the beam which is designed to carry a shovel. Each sleeve is provided with a slot, o, (see Fig. 4,)

to receive the bolt by which the shovel S is attached to the sleeve.

Heretofore the front of the sleeve along which the shovel is adjusted vertically has been curved, but so as to be concave; but the sleeves which I make are curved in the opposite direction and are convex, curving back from a point near the vertical center of the slot, as shown clearly in Fig. et. As a result of this form, if the shovel be lowered on the sleeve, it will stand more nearly perpendicular than before, and when plowing deep more dirt will be lifted out of the furrow. If the shovel be raised on the sleeve, its position will be less perpendicular than before, less dirt will be lifted, and it will not be lifted as high as if the angle of the shovel remained unchanged.

I have described the parts AA as together forming the arched axle, although the Wheels are not directly connected with these parts A A', which may be also regarded as forming a part of the frame of the machine.

What I claim as new, and desire to secure by Letters Patent, is as follows:

In a cultivator, the combination of an arched axle or frame, swinging shovel-beamsloosely connected with such axle or frame, a caster- Wheel, C, on one side and Wheel F on the other side supported on a short axle, fr', pivotally connected with the main frame, and connections between such short axle 7l and the adjoining shovel-bcam, Wl1ereby,whcn the shovels are moved out of line to the right or left, the Wheels and frame will move in the direction in which the shovels travel, substantially as specified.
